total flour = 2 + 1 + 1.25 = 4.25
would yield 4.25 cups * (1 doz / .75 cup) = 5.666666 or 5 2/3 dozen
total butter = 1/4 + 1/2 + 3/4 = 1.5
would yield 1.5 cups * (1 doz / 1/3 cup) = 4.5 dozen
well, we run out of butter after 4.5 dozen so we can make gooey paste with the left over flour.
Anita, Quentin, and Maria are baking cookies together. They need 3/4 cup of flour
and 1/3 cup of butter to make a dozen cookies. They each brought the ingredients they had at home. Anita brought 2 cups of flour and 1/4 cup of butter, Quentin brought 1 cup of flour and 1/2 cup of butter, and Maria brought 11/4 cups of flour and 3/4 cup of butter. If the students have plenty of the other ingredients they need (sugar, salt, baking soda, etc.), how many whole batches of a dozen cookies can they make?
